Canopy, snow, and lichens on woodland caribou range in southeastern Manitoba
Rangifer, 1996 I examined the relationships among snow cover (api), lichen abundance, and canopy composition on the range of the Aikens Lake population of woodland caribou (Rangifer tarandus caribou) in southeastern Manitoba.

Inferring the rules of social interaction in migrating caribou [PDF]
, 2018 Social interactions are a significant factor that influence the decision-making of species ranging from humans to bacteria. In the context of animal migration, social interactions may lead to improved decision-making, greater ability to respond to ...

Woodland caribou management in Alberta: historical perspectives and future opportunities
Rangifer, 2007 Woodland caribou conservation has been the topic of much debate for the past few decades. By the late 1970s there was growing concern about declining woodland caribou populations and the interaction between industrial activities and woodland caribou ...

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra
Ecography, EarlyView.Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

The need for the management of wolves — an open letter
Rangifer, 2007 The Southern Mountain and Boreal Woodland Caribou are facing extinction from increased predation, predominantly wolves (Canis lupus) and coyotes (Canis latrans). These predators are increasing as moose (Alces alces) and deer (Odocoileus spp).

Woodland caribou: Facts for forest managers
The Forestry Chronicle, 1992 A literature review points to predation as the proximate factor controlling woodland caribou (Rangifer tarandus caribou) populations in most cases, but that finding does not obviate the need for caribou to be included in forest management. Managers must consider the indirect effects of forest operations on caribou through their impacts on caribou ...

Comparative patterns of winter habitat use by muskoxen and caribou in northern Alaska [PDF]
, 1992 Thesis (M.S.) University of Alaska Fairbanks, 1992Snow depth and hardness strongly influenced selection of feeding zones, (i.e., those areas used for foraging), in late winter by both muskoxen (Ovibos moschatus) and caribou (Rangifer tarandus grand) in ...

Hot spots or hot moments? Contextualizing the spatio‐temporal scale of research on animal inputs
Ecography, EarlyView.Mammals play important roles in redistributing elements across ecosystems, concentrating biogeochemical inputs across both space and time. However, research on zoogeochemical inputs is often constrained by logistical considerations, potentially limiting our knowledge of mammals' impacts on biogeochemical patterns and processes.
